IMPROVEMENT IN LAMPBURNERs.

Specification forming part of Letters Patent No. 35,893, dated July 15,186:2.

To all whom, it may concern: l

Be it known that I, E. B. REQUA, of Jersey City, in the county of Hudsonand State of New Jersey, have invented a new and Improved Lamp-Burner,and I do hereby declare that the followingis a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making apart of this specification, in which- Figure 1 is aside sectional view of my invention, taken in the line m x, Fig. 2; Fig.2, a horizontal section of the same, taken in the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to a new and improved lamp-burner for burningcoal-oil; and it consists, first, in a novel and useful improvement inthe wick-tube, whereby much .broader wicks than usual may be employed inburners of a given size and a correspondingly broader dame obtained.

The invention consists, second, in a novel and improved means forelevating and lowering the wick, whereby the same will not be compressedinthe tube as hitherto and the free ascent of the oil retarded, and atthe same time the moving ol" the wick rendered certain, whether it bethick or thin for the tube, and capable of being moved or adj ustedwithin the tube with the greatest facility.

To enable those skilled in the art to fully lunderstand and construct myinvention, I will proceed to describe it.

A represents the cap of the burner, which is screwed into the top of thelamp, as usual, and B is a wick-tube, which is secured vertically in thecap A and passes up through a horizontal partitioma, in the upper part,C, of the burner. The lower part or cap, A, of the burner is perforated,as shown at b, for the admission o't' air, and the partition c is alsoperforated, as shown at b', the latter perforations being in a circularraised ledge, d, at the center of the partition and over which the coneor defiector D is fitted, the latter being perforated at its lower part,as shown at e.

The cone or deliector covers the upper part of the wick-tube B, and thelatter is of peculiar shape, being flat and straight at its upper partand bent at its lower part below the partition u, so as to be ofsemicircular form in its horizontal section, as shown clearly in Fig. 2at ax. This form of the wick-tube constitutes an important feature ofthe invention. It admits ot' the upper part ot' the tube beingcomparatively wide, as the lower part by being bent or curved, as shownand described, is materially contracted in width, so much so that it maypass through the screw portion f of a small-sized cap, while its upperstraight end will be much wider than the diameter of f. Hence I amenabled to use a much wider wick than usual in a burner of a given sizeand a proportionably wider ame obtained. Another advantage is obtainedby this bending of the wicletube, and that is that burners of varioussizes may be screwed into the same socket, g, on the lamp, which is animportant feat-ure, as it obviates the necessity of manufacturingdifferent-sized sockets to suit different-sized burners.

E represents a shaft, which passes horizontally into the burner and hasits bearings h h attached to the wick-tube B. This shaft is allowed toturn freely in its bearings, and it is provided. with a crank, z', whichis opposite the center and concave side of the wick-tube.

On the crank t there is tted a rod, F, the upper end of which has afork, G, composed of two or more tines permanently secured to it. Thesetines project from the upper end of the rod F at right angles, and theypass through' vertical slots j in the wick-tube and have their pointspressed into the wick k in the tube D by means of a spring, Z, which isattached to the lower end of the rod F and bears against a projection,m, at the bottom of the cap A, as shown clearly in Fig. l.

The shaft E projects at one end through the burner and has a smallthumb-wheel, n, at-

tached for the convenience of turning it. When the shaft E is turnedfrom left to right, the rod F is operated by the crank z', so that thefork G will be vshoved toward the wicktube D, and then upward, raisingthe wick, and then receding and moving downward and forward again towardthe wick-tube and upward. To lower the wick, the shaft E is turned in areverse direction. By this arrangement the wick is operated (raised orlowered) with the greatest facility and with certainty, and withoutbeing subjected to any undue pressure to retard the free ascent of theoil.

I do not claim raising and lowering the 2. Operating or raising andlowering the wick by means of a fork irrespective of the Wiel; 7sthrough the medium of the crank-shaft manner of operating the same; butE, fork G, and rod F, provided with the spring I do claim as new anddesire to secure by Z, substantially as described.
